A 32-year-old female asked:

Does orlistat interfere with the effect of multivitamins like vitamin c supplements and ferritin supplements? does orlistat stop them from working? i already have a healthy life style and eat less than my recommended calorie intake.

Orlistat: Orlistat interferes with the absorption of the fat soluble vitamins such as D A E and K. It shouldn't affect C, but can interfere with the absorption of certain medications. .If you're taking any prescription medications, check with your pharmacist about the advisability of taking Orlistat.
